-'Be it known that I, CHARLES M. LUNGREN,

' residing at Bayonne, in the county of Hudson and State of N .ew Jersey, have invented" certain new, and useful Improvements in.

Y Mantle Suspension, of which the following is satisfactorily to withstand the extremes of a'f ull', clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to oar-lighting 'sys- Y tcms,-- and particularly to means for suspendin-g fragile objects of the nature of incandes cent-lam mantles.

One 0 the objects-thereof is to provide simple and efficient means of suspension for articles of the above nature which will be able temperature use. v v I Another object is to provide durable means of the above type which will be of inexperh to which they are subjectedin' sive character and simple construction, yet

capable of resisting the vibration, shocks,

and jarsto which a car-lighting system is subjected. V Other objects will be'in part obvious and in l part pointed outhereinafter.

The invention accordingly consists in the features of construction, combinations ofele- .30

ments', and arrangement of parts which will be exemplified in the device hereinafter described and the: scope of the a plication of which willxbe indicateddn t, e following claims.

"In the accompanying drawings, wherein are shown two of various possible embodiments of my invention, Figurel is a sectional elevation of one of. the same. 1 similar view of the other thereof.

I heat to which they are subjected. Either of the aboveincidents .will result in the breaking of the mantle depending therefrom, as its integrity is dependent upon the preservation of the original shape of the member to which it is secured. Another point Whichis of infterest/here as-tending to render better'undere stood-certain features of my invention is that I have found it tobe desirable that-the man- -tle be held in fixed relationto the relatively rigid member from which itdepends, as in.

this manner relative movement-of these parts at their "junction, with a subsequent likeli hood of breaking the mantle, 1s obviated.v

The, difliculty of theproblem presented in constructing an efficient device which will carry a fragile gas-mantle safely-and for a The defects above indicated are done away with and many-practical advant'agesjhttainml in constructions ofthe nature ofthat heroin after described.- a g Referrin now to the drawings, there is shown in Fig. 1 what may be termed aflgas noz'zle] 1, which isformed-ofanydes1red material and serves not only to conduct the gas or other fuel to the point :of combustion, but also, in this illustrative embodiment, to

upper portion of the mantle, which as on". account of shrinkage-would tend to become. 95.-

I I

It may here be'noted that the Word cement is used throughout the following claims i'n abroad sense, as denoting any material which is adapted to be interposed between thesurfaces of two adjacentlmembers and adhere to I both of the same, thus connecting them one with another. The cement or paste used 10 preferably comprises a refractory oxid which. f

will become hard on heaLing-as, for example, thoria or magnesia, mixed to a cream with a material which will burn out upon being subjected to heat, as glue, or one that will remain and act as a flux, water-glass being an example of the latter class. It may here be noted that the term spool is used throughout this description and the following claims as having a broad and somewhat arbitrary meaning to denote any member which is adapted to have secured thereto an incandescent-lamp mantle.

The method of use of the above embodiment of my invention is as follows: The flame being directed downwardly toward the mantle strikes the lower end thereof and rolls back along the sides, thus bringing the same All jars, moreover, are to a certain extent cushioned by the fibrous spool 2 and any vibration or shock which is transmitted to the mantle 5 will not result in the same being swung against the supporting-spool, as these parts are rigidly held in fixed relation by the cement, as above described. Moreover, the relatively rigid yet somewhat elastic and yielding supporting-spool 2 is unaffected by the-heat to which it is subjected and on account of its low heat-conducting powers will not transmit the same to any appreciable de gree to the parts supported thereon. Also this spool is impervious to the effects of moisture and is unharmed by the changes in temperature, as well as by the excessive degree of heat to which it is exposed.

It Willthus be seen that I have provided means for supporting an incandescent-lamp mantle which are adapted to accon'iplish the objects set forth and which possess advantages many of which will be apparent from the above description and many of which can be appreciated only by a consideration of the exacting conditions to which the mantle is subjected in practical use. .I have found, moreover,that a threaded connectionbetween the spool and the member upon which it is mounted possesses distinct advantages in several particulars, as secure holding and ready detachability. The first cost of the parts is small and the labor required to assemble the same insignificant. Moreover, this mounting is characterized by marked durability and general efficiency under the severe conditions of practical use.

In Fig. 2 is shown an embodiment of my invention in which the same is applied to a mantle of a form in common use, adapted for use in connection with an upwardly-directed burner. The spool 8 used in this embodiment is similar in general construction to the spool 2 above described and maybe sup ported in any desired manner, as by an asbestos thread or projecting lugs, the same not being here shown, as it forms no part ofthe present invention. The means of securing the upper end of the mantle 9 to the spool are substantially identical to those above described with reference to mantle 5.

It may here be noted that the term mantle is used throughout this specification and the following claims in a broad sense as denoting any member adapted upon being exposed to the action of a source of heat to become incandescent and radiate such a considerable amount of light as to adapt the same for use as a source of li ht.

As many changes could e made in the above construction and many apparently widely different embodiments of my invention could be made without departing from the scope thereof, I intend that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense. I desire it also to be understood that the language used in the following claims is intended to cover all of the generic and specific features of the invention herein described and all statement of the sec e of the invention, which as a matter of anguage might be said to fall therebetween.
